Server Board Features

Hardware Requirements

To avoid integration difficulties and possible board damage, your system must meet the minimum
requirements outlined below. For a list of qualified components, see the links under
Information and Software."
Depending on accessory components selected, your server system may have additional
requirements not listed here. For example, to use the integrated Intel® RAID Controller
SROMB4UE option, you must purchase and install both the Intel® RAID Activation Key and one
DDR333 128 MB DIMM or the Intel® Portable Cache Module. The documentation provided with
these accessories outlines the hardware requirements and dependencies to install them.
Processor
Up to two Intel® Xeon™ processors can be used. These must have frequencies starting at 2.8 GHz
using the 90 nanometer technology and utilizing an 800 MHz front side bus. Previous generations
of the Intel® Xeon™ processors are not supported.
When two processors are installed, both must be of identical revision, core voltage, cache size, and
bus / core speed. When a single processor is installed, it must be in the socket labeled CPU_1.
See Supported Processors.
System Memory
The Intel® Server Board SE7520AF2 includes four banks of DIMMs across two channels. Channel
A consists of DIMMs 1A, 2A, 3A, and 4A. Channel B consists of DIMMs 1B, 2B, 3B, and 4B.
Bank 1 (DIMMs 1B and 1A) are closest to the edge of the server board. DIMMs must be identical
within each bank.
The minimum allowed memory is 256 MB, using a single 256 MB DIMM in either DIMM socket
1B or DIMM socket 1A . The system operates in single channel when only a single DIMM is
installed. The maximum allowed usable memory is 16 GB, using 2 GB DIMMs.
DIMMs must meet the following requirements:
Use only DDR2-400 ECC, registered DDR DIMM modules
DIMM organization x72 ECC
Use 240-pin DIMMs
DIMMs of the following size can be used: 256 MB, 512 MB, 1 GB, and 2 GB.
For a complete list of supported memory DIMMs, see
The Intel® E7520 chipset includes hardware that supports memory mirroring and memory on-line
sparing. Both memory mirroring and memory on-line sparing provide a way to prevent data loss in
case a DIMM fails.
